AApplication tiled September 7, 1882. (No model.) Patented in Belgium March 17, 1877, No. 41,748 in France November 29, 1880,

and in Germany July 10, 1881.

To all whom it may concern:

Be it known that 1, CHARLES LIEVENs SOYEZ, of the city of Brussels, in the K ingdom of Belgium, have invented certain Improvements in Elevators, of which the following is a specication, reference being made to the accompanying drawings.

My invention relates to that class of elevators in which the car or truck works on an inclined plane, and is adapted to receive upon it ordinary railway rolling-stock or any other loads whatever.

The invention consists in the combination, with inclined tracks or ways and a car or truck adapted to travel thereon, of a hinged or vertically-movable platform surmountin g said car or truck, a yoke or draft device` to which the cable or chain whereby the car or truck is moved may be attached, and a novel system of brakes adapted to acton said inclined tracks or ways, all being combined and'organized so that the weight of a load upon the aforesaid hingedplatform will, when the draft cable or chain breaks, throw the brakes into action and prevent the descent of the car or truck and its superposed load.

In the accompanying drawings, Figure l is a side elevation of an elevator adapted to travel on inclined tracks or ways and embodying myinvention. Fig. 2 is a plan thereof, the superposed hinged platform being removed; and`Fig.3 is a transverse section of the apparatos.

Similar letters of reference designate corresponding parts in the several figures.

D is the frame or truck, mounted on axles and wheels to run on the inclined rails b b of the inclined plane; and F is the table or platform, hinged to the said fralne or truck D at E in such manner that it may remain h orizontal during the movement of the apparatus on the inclined plane. The table or platform F may be furnished with rails in such manner as to be capable of receiving upon it ordinary railway rolling-stock, or to receive any loads whatever, and carries at G a hanger to receive and guide'the draft device.

To the lower part of the frame or truck D, and lengthwise of it, are secured two bearers,

H H, supporting the fnlcrums I I ofthe brakeallelogranl and to the bearers H H there may y be attached as be desired.

XV is an elbow-lever, having for its `fulcrum an axle, w, which is supported in the frame D, and having two branches,the one,'l, entering a cavity, S, in the end of the parallelogram K L M many brake-levers J J as may N, and the other, U, supporting at its extremity the platform or table F. To the extremity, V, of the long arm X of the lever is connected by a chain the draft device, which, as shown, consists of a yoke, W, and to which the draft rope or chain is attached. When the draft is applied to the yoke W and through it to the chain the long arm of the lever X is pulled down and the branch U raises the platform F andthe branch T, moving the parallelogram, disengages the jaws of the brake-levers J J from the rails, and while the draft chain or rope is tight the brakes are free from the rails. The chain or rope being broken, the platform F, pressing upon the branch U, causes the arm l T to move back the parallelogram in such manner as to produce the biting or clamping of the brake-levers on the rails and stop the de scent ofthe apparatus on the inclined plane b b, the biting or clamping action being more powerful in proportion to the load on the plat form F.

To prevent a vehicle on the platform F from running forward when such vehicle, at the moment of the stoppage of the frame or truck, tends to run forward by reason of the slight lowering of the forward end of the platform, a stop-lever, Z, is applied to the platform.

At the extremity of-theV parallelogram to which is adapted the extremity of the branch S of the lever X one or more springs are applied to the frame or truck D to prevent shock in starting and to start the lever toV produce the operation of the brake-levers when the traction rope or chain breaks or ceases to act.

vWhat I claim as my invention is- 1. The combination, with inclined tracks or ways, and a car or truck movable thereon, of

IOC

a hingedor vertically-movable platform surmounting said car or truck and adapted to receiv-e a load, a draft device, to which the draft l cable or chain is to be attached, and a system of brakes adapted to act upon said inclined tracks or ways, all being so constructed and organized that the weight of the load on said platform will throw the brakes into action when said draft cable or chain breaks, substantially as herein described.

2. The combination of the inclined tracks or ways b, the car or truck movable thereon, Ithe brakes J J J J", the movable frame whereby said brakes may be thrown intofaction, the movable load-supporting platform F, the lever X, comprising the arm T, which engages with said frame, and the arm U, upon which said platform F rests, and the draft deviceW, connected with the rear end of vsaid lever, substantially as herein described.
